Same output, but it states the intent: leave a SecretString whole rather
than transform it. The comment now separates the two lines by what they
do, because they are not the same kind of thing - the policy is the
protection, and without it a masked object is written out property by
property, while this line only decides whether a secret reads as its
length or as {"HasValue":true}.
